Heating the pool at a low cost or in winter is possible. A swimming pool heat pump, a sun cover, a heat exchanger or electric pool heater with solar panels raise the temperature of your pool inexpensively. Heating your above ground or underground pool is easy!

Why heat your pool?

ManoMano

To swim in Spring,  Autumn and Winter -  to swim all year round!

 If the weather is harsh and the temperatures are low, the water in your pool can become cold and make swimming unpleasant if not impossible.

Heating your pool brings well-being, ensures a  relaxing time and extends the summer season.

If you wish to make the most of your pool before and after the season, installing a pool heater, a system for raising temperature of your pool’s water is paramount.

How to heat your pool inexpensively?

ManoMano

 

Heating your pool at a low-cost is possible by using solar heating, bubble covers, a pool shelter, a heat pump and heat exchanger which have boilers.

Solar pool heating

First I will refer to the installation of solar panels which produce electricity in order to feed a heating system like an electric heater, a solar pool heater is economical, easy to install and reliable but only performs in sunny areas and space is needed for the installation of solar collectors. The principle of a solar pool heater is simple: water, injected by the pool pump via a derivation or by a secondary independent pump, is heated in a circuit of black polypropylene tubes before being reinjected into the pool via the nozzles or an accessory nozzle. All of these pipes constitute what is called a solar carpet, the water is heated there; they can also be assembled in a dome.

The solar cover, also called bubble cover or sun cover, allows you to increase the temperature of the water in your pool a few degrees. Practical and economical, the solar cover cannot be used while swimming since it covers the pool, by covering it, the solar cover also reduces the evaporation of the water which reduces the supply of cold water.

A pool shade created by the greenhouse effect heats the water in your pool and maintains a higher temperature than outdoors, it can be considered as “solar heating” for these reasons and depending on its height, a pool shelter allows you to bathe on windy days and greatly reduces the cooling down of your pool water.

Heating your pool, with solar energy means heating your pool for free – excluding the cost of installation and equipment acquisition of course!

Which system to use to heat your pool?

ManoMano



There are three distinct pool heating systems: the electric heater, the heat exchanger and the heat pump.

Electric pool heater

An electric heater heats your pool via a resistance and is installed in the filtration network between the pump and the nozzles. Compatible with some outdoor pools, the electric heater is sized according to the temperature and the volume of the water. Easy to install, it is energy-intensive however: pay attention to the bill! Combining the electric heater with a solar panel installation is an alternative to its high energy consumption.

Pool heat exchanger

The heat exchanger is economical, easy to install and allows you to increase the temperature of your pool’s water by using the heat pump or the boiler of your house! The heat exchanger allows a rapid rise in temperature through a heat exchange from one circuit to another and is also sized according to the volume of water of your swimming pool.

Pool heat pump

A heat pump gives your pool a pleasant temperature and ensures prolonged use before and after the season. A heat pump has the best performance, is installed outside and is positioned in the filtration circuit. Like the heat exchanger and the electric heater, the heat pump is sized according to the volume of the water and with coefficients relating to the installation area.

How to choose your pool heating system?

ManoMano

 

Heating your pool with a cover, an exchanger, a heat pump or solar energy: all pool heating processes are to be considered and some may be complementary – a solar cover can be combined with an electric heater and a solar carpet.

Some heating systems are energy-intensive - electric heaters – and others more economical in the long term but more expensive to buy - a pool heat pump.

A heating system is chosen according to your requirements in terms of comfort, your pool, your ancillary equipment, your use and your budget. Of course, the heating of the water of your swimming pool is combined with cleaning and maintenance: the hotter the water, the more it is prone to the proliferation of bacteria!

A l’issue d’études dans le commerce, j’ai appris par opportunité la profession de charpentier. Noble mais dur métier, les hivers et la pluie m’ont incité à descendre des toits et à pousser les portes d’une quincaillerie où sans grande surprise, je me suis retrouvé quincaillier.

De vis en boulon, j’ai travaillé au fil des années dans tous les rayons de magasins de bricolage où j’ai eu le loisir d’apprendre l’utilité et le fonctionnement de tout ce qui s’y vendait. Entre deux magasins, je n’hésitais pas à travailler comme serrurier, couvreur, menuisier ou dans le secteur industriel.

Mon expérience terrain conjuguée à mes connaissances techniques me permet de jauger le vrai du faux dans le choix des outils et équipements. Préférant restituer un conseil désintéressé à l’écrit que me répéter du lundi au samedi dans un magasin, il était naturel que je me dirige vers le métier de rédacteur.
